“The Sunstone team includes former installers, so they've been in our shoes. Commercial financing has been an industry pain point over the last decade, but with Sunstone’s unique product offering, we’ve been able to close several deals that wouldn’t have been financeable before. We're looking forward to growing our partnership with Sunstone as we work to scale the transition to a renewable based economy in the mid-Atlantic.”
